Chihuahuas may be tiny, but they come with big personalities and unique needs. Before you welcome one into your life, it’s worth knowing the less obvious realities of living with this spirited breed. Here are seven things seasoned owners often wish they’d known from the start.

1. Their Size Can Be Deceiving

At first glance, you might think a Chihuahua’s small frame means they’re delicate and easygoing. In truth, they often act like they’re the biggest dog in the room. That confidence is part of their charm, but it can also get them into trouble with larger dogs if not managed carefully.

2. They Feel the Cold More Than You’d Expect

Chihuahuas are prone to shivering even when it’s not freezing outside. Their thin coats and tiny bodies lose heat quickly, so sweaters and cozy blankets aren’t just cute accessories — they’re practical essentials.

3. Training Needs to Start Early

Because they’re small, people sometimes overlook discipline, assuming their antics aren’t a big deal. But an untrained Chihuahua can be surprisingly bossy and vocal. Early, consistent training helps shape them into polite companions without dimming their spirit.

4. They’re Often Velcro Dogs

Chihuahuas form strong attachments to their people and may want to be near you almost constantly. While this can be heartwarming, it also means they may struggle with being alone for long stretches.

5. Their Health Needs Can Be Breed-Specific

Chihuahuas are prone to certain issues like dental problems and patellar luxation. Staying ahead with regular vet visits, tooth brushing, and joint care can prevent bigger problems down the road.

6. They’re Sensitive to Rough Handling

Because of their size, even an accidental drop from a short distance can cause injury. Families with young children need to be extra mindful about handling them gently and supervising interactions.

7. They Have Endless Energy in Short Bursts

They might not need marathon walks, but Chihuahuas thrive on short play sessions and mental stimulation. Without enough to do, they can channel that energy into barking or mischief.

A Chihuahua’s companionship can be incredibly rewarding, especially if you understand what makes them tick before they join your household. With the right care and attention, their bold little hearts will make a huge place for themselves in yours.
